4 Claims. (Cl. lOl-377) This invention relates to a roll type die holderto be mounted upon a shaft and rolled upon a surface to form an imprintof the dies upon such surface.

An object of the invention is to provide a type or die holder in whichthe type or die members are securely held in place at all times.

Another object is to provide a roller type of die holder which is soconstructed that the component parts thereof may be adjusted to rigidlyreclamp the type or die members when such members become slightlydeformed from rigorous use to which they are subjected when in normaluse.

A more specific object is to provide a holder comprising, in a preferredform, side plates and inwardly extending lugs intertitting in a mannerto provide a recess for a font of type and a second recess for a wedgeand means for moving the wedge to maintain the font of type securewithin the first mentioned recess.

Other objects and 'advantages of the invention will be more fullyapparent from the following description and the accompanying drawings inwhich:

Fig. l is an elevational view of a holder embodying the invention;

Fig. 2 is a sectional view taken on line 2 2 in Fig. l;

Fig. 3 is an exploded View in side perspective of the embodiment shownin Figs. l and 2;

Fig. 4 is a detail sectional View on line 4--4 of Fig. 2 showing a dieor type in place within the holder.

The embodiment disclosed comprises a hub member 1, adapted to be mountedupon a shaft, and a pair of side plates 2 and 3 having central openings4 and 5 to fit upon reduced end portions 6 and 7 of the hub.

Each of the side plates 2 and 3 has an axially extending lug 8 so thatthese lugs interiit in angularly spaced relation when the plates areassembled in side by side relation upon the hub 1. The lugs 8 are ofsuch height that there is formed a slot or recess 10 of sufficienttransverse dimension to receive the type or die blocks 11. The arcuateextent of Vthese lugs is also such that the slot 10 is of a length toreceive the desired number of type and spacer blocks to imprint desiredinformation, and also to provide a space or recess opposite the typeslot 10 to receive a wedge block 12 having its converging side facesriding upon the end faces 13, 14 of the lugs 8.

The wedge block 12 has a hole therein to receive screw 20 which enterscomplementary threaded hole 21 so that turning of the screw to advancethe wedge toward the axis of rotation of the holder causes the wedge 12to force the lugs 8 apart and consequently to reduce the arcuate extentof the slot 10.

In order to permit this relative rotational movement between the sideplates 2 and 3 the lug portion of each of these plates is provided withone or more arcuate slots 22 counterbored at 23 to receive the head 24of a screw 25.` The opposing side plate has a threaded opening 26opposite each of these slots so that, upon tightening of all of thescrews 25, all parts of the holder assembly and the type 11 therein areheld in assembled relation.

2,910,938 Patented Nov. 3, 1959 It is also to be noted that the sideplate 3 is recessed at 29 concentric of its axis so that lugs 30 on thetype or die 11 fit therein. 'Ihus the type 11 is held within the slot 10and with the inner end of the type in engagement with the periphery ofthe medial flange portion of the hub 1.

By way of further description and explanation of assembly, adjustmentand use of the holder it will be assumed that the end plate 3 is laidupon a flat surface and a font of type and spacers of sufficient arcuateextent to fill the slot 10 is placed thereon, the lugs: 30 on the typeentering the recess 29 and the inner ends of the type being in abutmentwith the periphery of the hub 1. The screw 20 is loosened so that thewedge 12 may move to an outer position to provide sufficient space forthe lug 8 on the plate 2 to enter between the front of type and thewedge.

Plate 2 is then superposed upon the assembly as thus far described, thereduced end portion 6 of the hub 1 entering the central opening in theplate as the lug 8 enters between the font of type and the wedge 12.Screws 25 are then inserted and tightened suiciently to hold all partsin assembled relation. Screw 20 is tightened to move the wedge 12inwardly and force the lugs 8 apart whereby the font of type is wedgedtightly endwise in the slot 10. Screws 25 are now fully tightened andthe holder is fully assembled ready for use.

It seems apparent that any endwise looseness of the font of type due toslight deformation thereof or of the holder from stresses set up in theholder when in normal use may be readily compensated by tightening ofthe screw 20. Hence, satisfactory operation and long life of the holderare assured.

The invention claimed is:

1. A roll type die holder assembly comprising a pair of opposed sideplates each having an axially extending lug, said plates beinginterconnected with the lugs interfitting and forming a first recessadapted to receive a font of type and a second recess annularly spacedtherefrom, and wedge means in said second recess engageable with saidlugs and movable radially of the assembly to produce relative rotationbetween the plates and effect clamping action upon the ends of the fontof type.

2. A roll type die holder assembly comprising a pair of opposed sideplates each having an axially extending lug, said plates beinginterconnected with the lugs interlitting and forming a first recessadapted to receive a font of type and a second recess annularly spacedtherefrom, wedge means in said second recess engageable with said lugsand movable radially of t-he assembly to produce relative rotationbetween the plates and effect clamping action upon the ends of the fontof type, and additional means for producing axial clamping action uponthe side plates and the font of type.

3. A roll type die holder assembly comprising a pair of opposed circularside plates each having an arcuate axially extending lug, said lugsinterfitting and forming spaced annular recesses in the holder, one ofsaid recesses being adapted to receive a fontV of type, means forrestraining said type from radial outward movement from within therecess, a wedge in the other of said recesses, and having its side facesin engagement with the end faces of said lugs, and means for moving saidwedge radially inwardly to produce relative rotation between the sidemembers to clamp the font of type within said first mentioned recess.

4. A roll type die holder comprising, two generally circular sidemembers having axial openings therein, a hub fitting within saidopenings and having a peripheral flange extending radially between theside members, a pair of lugs interposed between the side membersoutwardly of said flange, said lugs being circumferentially spaced andforming with the side members and the periphery of said flange anarcuate recess for a font of type and a second arcuate recess spacedfrom said rst References Cited in the le of this patent mentioned recessand adapted to receive a radially mov- UNITED STATES PATENTS able wedge,a wedge in said second recess, means for moving said vwedge to move saidlugs into clamping en- 1 r's ""Sutg" gagement with a font of. typewithin said rst mentioned 5 2358674 W eb er Sp 19 1944 recess, and meansfor producing a transverse clamping 214091409 Wild Oct 15 1946 actionupon said side members so that the component parts of the holder and afont of type therein are secured FOREIGN PATENTS in assembled relation.465.,.631 Germany Sept. 24, 192,8
